Re: I lost my red feather couter...
Since the pieces don't actually need to be randomly drawn, and thus don't need to be identical, it's perfectly okay to play with a home-made replacement piece.
If you wish to get the actual game counter, try contacting the game's publisher to see if they have replacement bits available.
If that fails, go to your collection entry and post that you "want parts" for this game.
What I'd do is photocopy the existing red feather counter (you should have at least 2 if I recall) and paste the copied images to some photo framing mat, which you can get at a craft store for not much money. You'll have a fairly accurate and nicely made substitute.
